Infleqtion Receives £9 Million to Develop Quantum RF Sensing System

Insider Brief

• Infleqtion has received £9 million from Innovate UK to develop Quantum Spectrum-DF, a deployable quantum radio frequency direction-finding system under the second phase of the QuDiFi project.
• The system uses Rydberg atoms and optical techniques to detect and locate radio signals, with the aim of reducing reliance on large antenna arrays.
• Developed in collaboration with Leonardo, the technology is intended for defence and civilian applications, including spectrum monitoring, passive radar, and resilient navigation.

PRESS RELEASE — Infleqtion (NYSE: INFQ), a global leader in quantum computing and quantum sensing powered by neutral-atom technology, has been awarded £9 million (~$12M) by Innovate UK, part of UK Research and Innovation (UKRI), to continue development of a deployable quantum radio frequency (QRF) direction finding (DF) system as part of the Quantum Missions Primer programme. Infleqtion is developing a Quantum Spectrum-DF product within the second phase of the Quantum Direction Finding (QuDiFi) project, designed to accurately detect and locate signals in environments where existing technologies are limited.

“By advancing quantum sensing from laboratory research to practical deployment, this project will help establish the United Kingdom as a leader in next generation radio frequency sensing technologies,” said Colin Sullivan, Managing Director, UK at Infleqtion. “The technology also lays the groundwork for future applications such as spectrum surveillance, passive radar and resilient navigation, enabling new capabilities that are not achievable with existing systems.”
